With complete qualifications, we serve the whole country and solve various electrical and explosion-proof fire problems for our customers.
Testing regulations and requirements of relevant standards:
According to Article 5.5 of the Verification Regulations for Combustible Gas Alarm Devices (JJG693-2011), the calibration cycle for combustible gas detection and alarm devices is generally not more than one year. If there are doubts about the measurement data of the instrument, or if the main components of the instrument are replaced or repaired, it should be promptly sent for inspection.
According to Article 3.5 of the "Specification for the Use of Combustible Gas Detection and Alarm" (SY6503-2000), combustible gas detection and alarm devices in use should be calibrated regularly according to regulations
According to Article 7.2.1 of the "Specification for the Installation of Toxic Gas Devices in the Workplace" (GBZ/T223-2009), the detection and alarm devices shall be calibrated regularly according to the manufacturer's specified time and procedures.
According to Article 3.4 of the "Specification for the Use of Combustible Gas Detection and Alarm Devices" (SY6503-2000), the combustible gas detection and alarm devices installed and used should be manufactured with measuring instruments recognized by national institutions and have explosion-proof performance**
